Pamela,
We were originally booked in cabin 6136 on the Infinity Dec. 15 cruise but were given the opportunity to take cabin 6143 (which we did!!). We looked at 6136 on the morning we ended the cruise. It was a nice cabin, but was not quite as large as 6143/6144. The balcony was large (but not quite as large as 6143/6144) enough to have two padded lounge chairs as well as the two regular straight chairs. (6143/6144 had these as well.) I did notice that the sitting area in 6136 consisted of just a chair and small table as compared to a couch and table. If I could not get 6143 or 6144, then these two cabins would be my next choices because of the great location and the LARGE balcony!!
